TOOL GUARD.

Application filed July 14,

Artisans and others engaged in work resulting in the violent throwing off of particles, such as the heads of rivet-s when cutting off the same, or the flying of chips when cutting metal. stone and the like, frequently in jure' others and themselves by wholly or partly destroying the sight when the eye is struck by or receives a particle which lodges therein.

The present invention provides an attachment which arrests the flight of such particles as rivet heads and chips, and which may be mounted upon the arm, or other convenient part of the workman, or upon the tool, said attachment being light, adjustable to meet all conditions and of a nature not to interfere with or prevent observation of the work.

VVh-il e the drawings illustrate a preferred embodiment of the invention, it is to be understood that in adapting the means to meet specific needs and requirements, the design may be varied and such other changes in the lninor details of construction may be resorted to within the scope of the invention as claimed, without departing from the spirit thereof.

For a full understanding of the invention andthe merits thereof, reference is to be had to the following description and the drawings hereto attached, in which,

Figure 1 is a perspective view illustrative of an embodiment of the invention.

Figure 2 is a diagrammatic view of the cuff or band and the parts intimately associated therewith,

Figure 3 is a transverse sectional view of the cuff or band and the parts mounted thereon,

Figure 4 is an enlarged sectional view about on the line 4-4 of Figure 2 showing a portion of the guard,

Figure 5 is a detail sectional view on the line 5 5 of Figure 1, and

Figure 6 is a detail view of a. modification, wherein the guard is mounted directly upon the tool.

Corresponding and like parts are referred to in the following description and designated in the several views of the drawings by like reference characters.

The numeral 1 designates a type of tool for which the invention is chiefly designed, and the same may be of any shape and adapted to be operated electrically or by fluid pressure, such as compressed air. The

1926. Serial No. 122,479.

tool 1 has a chisel applied thereto and this chisel may be of any formation depending upon the nature of the work and the specific character of the tool. In Figure 1 the tool is shown as applied for cutting off the heads of rivets, and these heads, when detached are thrown off with violence and frequently cause injury and the loss of sight. The same is true of anaiogous tools used for chipping metal, stone and the like, the cuttings or detached particles flying through the air with such velocity as frequently to cause injury.

The present invention disposes a guard in such a manner as to arrest the flight of the particles when detached. thereby preventing injury to the workman and to others. The guard may be mounted upon a convenient part of the workman, such as the forearm. as indicated in Figure 1, or it may be mounted directly upon the tool, as indicated in Figure (5 of the accompanying drawings. In either case, the guard is adjustable and of such formation as not to obstruct ready observation of the work or interfere with the progress of the work. In the preferable construction the guard is light and of flared formation, and comprises a frame 1 and a covering 2 preferably of tex tile, such as canvas. The frame 1 flares throughout its length and is constructed of stout wire bent into the form substantially as shown. A window frame 3 is provided at the inner or smaller end of the guard frame 1 and receives a transparent panel 4 which admits of ready observation of the work. A stem 5 projects rearwardly from the lower end of the window frame 3 and provides ready and convenient means for coupling the guard to a flexible tube 7 such as commonly employed for supporting lighting fixtures and other articles required to be supported in a manner to admit of adjustment. A spring catch 8 associated with the socket 6 prevents casual displacement of the guard when coupled to the flexible tube 7.

The flexible tube 7 is provided at the end opposite the socket 6 with a plug 9 which is adapted to be coupled to the socket of a member 10, which may be attached directly to a convenient part of the workman, such as the forearm, as indicated in Figure 1, or directly to the tool, as shown in Figure 6. The coupling member 10 may be provided with clamps 11, as illustrated in Figure 6,

whereby it may be attached to the body of the tool 1, or it may be formed upon a base plate 12 which may be riveted or otherwise secured to a cuff or band, as shown in Figure 1, and the detail views thereof. In either mounting of the guard the latter may be adjusted, so as to overhang the chisel 2 or like tool, whereby to intercept the detached particles, such as the heads of rivets or chips of metal, stone, or the like.

The cuff or band comprises a middle section 13 and side sections 14 and 15. These sections preferably consist of a single piece of leather or other appropriate material which is suitably lined. A flap 16 is provided at one end of the cuff or band to close the space and underlap the fastenings by means of which the device is secured to the forearm of the workman. Straps 17 are provided at opposite ends of the cuff or band to secure the same when positioned upon the arm of the workman, the said straps being connected by buckling in a manner well understood. A reinforcing plate 18 is placed L against the inner side of the middle section 13 and the two plates 12 and 18 are connected by means of rivets 19 or like fastenings. A pad 20 covers the plate 18 and is stitched to the middle section 13. The socket end of the coupling member 10 is deflected away from the cuff or band at a slight angle to give a proper set to the flexible tube 7. The cuff or band may strengthen and brace the wrist and forearm of the workman, besides forming convenient means for attaching the guard or shield to the person of the workman. In ractice, the guard, whether mounted upon t e forearm, or directly upon the tool may be adjusted so as to arrest and prevent the flying of particles, such as rivet heads, metal chips and the like to an extent to injure the workman or others, as frequently happens when such particles are permitted to fly promiscuously when detached.

Having thus described the invention, I claim:

1. A tool guard comprising a cuff, means for securing the cuff to the person of the workman, a coupling member mounted upon the cuff, a flexible tube connected at one end to the coupling member and a guard coupled to the opposite end of the flexible tube.

2. A tool guard of the character specified comprising a cufi', means for securing the cuff to the arm of the workman, a reinforcing plate applied to the cuff, a coupling member connected to the cuff and reinforcing plate, a flexible tube attached at one end to the coupling member and a guard at the opposite end of the flexible tube and including a Window to admit of unobstructed observation of the work.

A tool guard comprising a flared frame of light material, a window frame pendant from the'contracted end of the flared frame, a textile covering the flared frame, a transverse panel fitted to the Window frame, and means connected to the window frame for adjustably mounting the guard.

In testimony whereof I affix my signature.
